CARTON Filed March 19, 1948 5 Sheets-Sheet 4 Patented Feb. 23, 1954 UNITED STATES L PATENT OFFICE CARTON- William P. Frankenstein, Cincinnati, Ohio Y Application March 19, 1948, Serial No. 15,871 Claims. (Cl. 229- 3 1) This invention relates to improvements in cartons and particularly to improvements in cartons or boxes of the knockeddown variety formed from a single blank of card or paper-board material having, when erected, a platform intermediate the height of the walls.

Foldable or knocked down boxes or cartons having a partition or platform intermediate the upper and lower ends of the walls are not necessarily new with this application except to the extent of improved construction and added rigidity and strength together with ease of op eration in the setting up-of the box or carton from the said knocked down position.

The primary object of'thepresent invention is the provision-of an improved knocked down box or carton that can be erected from the flat to provide a platform for the .box extending transversely thereof between the walls and intermediate the height of said walls.

Another object of this invention is the provision of a knocked down box or carton that can be readily set up with a minimum of effort for automatically positioning'the walls of the box or carton normal to the base and automatically positioning and locking a platform upwardly of the base.

Another object of this'inventionis theprovision of a box or carton that is automatically folded to its knocked down position subsequent to the blanking out of the blank f-rom"which the carton is subsequently erected, said folding being done with subsequent erection in mind whereby the box or carton can -be readily erected when desired for use. a v a A further object of the present invention is the provision of a box or carton having a plat'-' form upwardly of its bottom necessitating folding of the blank to have several portionsthereof superimposed on one another withportionsof said superimposed layers adhesively'connectedi to one another and wherein the blank is so designed that the adhesively'attached artsgare subjected to equal and proper pressures-in effecting their attachment l A still further object of the present invention is the provision of a carton or box formed' from' a single blank and'having walls and a platform in which the several walls and members thereof as well as the platforminterengage' iwithi'one another in holdingthe' walls in assembled landerected positions.

Other objectsand advantages ofthepre'snt invention should be readily apparent'by referis to the qwia r e flc iienfi n r dl conjunction with the accompanying drawings forming a part thereof and it is to be understood that any modifications may be made in the exact structural details there shown and described, within the scope of the appended claims, without departing from or exceeding the spirit of the invention.

flhr'oughout the several views of the drawings similar reference characters are employed to denote the same or similar parts.

The carton or box blank of Fig. 1 comprises a panel '25 having its sides or edges defined by score or' fold lines 26, 27, 28 and 29. For the purposes of description and identification the score or fold linesZ'l and 29 will be referred to as the sides while the score or fold lines 26 and 28 will be'referred 'to as th'e'ends but it is to be understood that these terms are interchangeable. The bottom panel has ccnnectedto its one side an extensionilfl which in the erected carton forms one side wall and the carton platform while the bottomjfi has connectedto its other side an extension 3'! which'forms in the erected carton a second side wall. 7

p The extension 30 is longitudinally' divided by parallel score or fold lines-32, 33, 34, 3'5, 36 and 3'! into panelstll, 38,, 40, 41, 42, 43 and 44. In theerected'carton the panel 38" forms one side wall outer wall member havingits ends defined by score or fold lines 45 and '46 which are in substantial alignment with the bottom panelkend score or fold lines '26 and'2 8. The panel 39 has its ends defined by outlines and 48 and con stitutes in the erected carton one side wall top wall member and is positionedsubstantially par allel withfthe carton bottom panel 25. The panel 40 in the erected carton forms the side wall inner wall member and has its ends defined by score'or fold'lines 49' and 50 which integrally hingedly connect to said panel 40 flaps 5i and 52. The flaps SI and 52 are in turn, each, divided by a score or fold line 53 which, respectively, integrally hingedly connect to the flaps 5i and 52 spacer tabs 54 and 55. In the erected carton the panel 4| forms the platform upwardly spaced from the bottom panel 25 and has its ends defined by score or fold lines 55 and 51' which in-' te'grally hingedly connect thereto brace flaps 58 and 59. The panel 41 is illust'ratedas having within its borders, in phantom lines 60, a cutout which is provided, as is usual practice, for receiving the body, portion of an article to be displayed and shipped therein.

. In the erected carton the panel 42 forms a supportfor the longitudinal edge of the platform panel 40 and has its sides defined by cut lines which are inwardly spaced from the platform ea ls nrsto el ic lines n 51 n. a ount.

equal to the thicknessof the box material since this brace depends between said platform end and the end walls. The panel 43 constitutes in the erected carton a sub-bottom and is placed in face contact with the carton main bottom panel 25 for thereby strengthening said carton bottom. The panel 44 in the erected carton forms in part a brace for the other longitudinal edge of the platform panel 41 and in part a glue flap whereby the panels ar hinged to one another for subsequent erection in spacingfthe platform 4| from the carton bottom panels 25 and 43. In the final position of the panel 44 it constitutes a portion of the side wall inner wall member along with the panel 40 and is provided inwardly thereof and adjacent itsends with notches 6! and 62 which are superimposed on elongated apertures 63 and 64 in the pane'1'49 and wherein said elongated apertures 63 and 64 are formed inwardly, in the erected carton, upwardly, of the score or fold line 34 at one side of the panel 40.

The side wall extension 3|, similar'to the side wall and platform extension 30, is longitudinally alignment withthe bottom panel end'scores 2B and 28. The panel 58 in the erected carton forms the said second side wall'top wall member and has its ends defined by cut lines '12 and '13. The panel 69, in the erected carton, forms the second side wall inner wall member having its ends for the major portion thereof defined by scoreor fold lines 74 and 15 which integrally hingedly connect thereto tucking flaps l6 and H. Said tucking flaps l6 and 11 are in turn, each, divided by score or fold lines [8 which respectively hingedly connected with the tucking flaps 16"and Tl spacer tabs 19 and 80. The portion of the panel 69 beyond the tucking flaps 16" and 11 act as a glue flap in hingedly connecting the parts to one another. The second side Wall inner wall member or panel 69, similar to the panel 4!), is provided with elongated apertures 98 and 99"in'- wardly of its end scores 14 and '15 with said aper-- tures 98 and 99 extending inwardly, in the erected carton, upwardly, of the portion of said panel which constitutes the glue flap. 7

The carton bottom panel 25' has hingeclly connected thereto through its end scores 26 and28 extensions 8i and'82 which in the er'ectedcarton form the end walls and since saidextensionsBl and 82 are substantial duplicates of one another it is deemed sufiicient if but one of-thein'be' described in detail.

Accordingly, extension 8| is provided longitudinally thereof witha plurality of score or fold lines 83, 84 and BE thereby providing in saidextension between the score or fold line 26and its end, panels 86, 81; 88 and 89.

In'the erected carton thepanel' Stfbrms'the end wall outer wall member having its ends de finedv by score or fold lines 90' and 9| which are in alignment with the carton bottom panel side scores 21 and 29. The panel 81 in the erected carton forms the end wall top wall member with its ends defined by cut lines in alignment with the score or fold lines 9'!) and 9l,.while the panel 88 forms the end wall inner wall member. Since the end wall inner wall member, in the erected carton, is positioned between theside walls inner wall members its lengthis less than thatof the end wall outer wall member by so much as constitutesthe combined widths; ofside walls top w m sor anelsihandqfls d ndwa l' n r. wall mbe q pane 88, a its end n. h ai fi edhyQrqqri lines 92 and 93 which hingedly connect theretospacer tabs 94 and 95. Beyond the said scorc QIQIQ Q lines 92 and 93 the panel 8 8, has projecting therefrom looking lugs 96 and 91 which in the erected carton, respectively, enter the side walls opposed elongated apertures 63 and 64and 98 and 99 v ..,,The side andend walls outer wall members have between their adjacent ends similar corner pieces I03 each of which is divided by a score or-fold line I04 that extends diagonally thereof from its innermost corner to its outermost corner. Said corner pieces I03 are known as a bellows corner having the portions thereof on opposite sides of its score or fold line I 4'folded on one another in the erected carton as will presently be made clear. I j

The blank after being cut and scoredas just described is provided with a band of adhesive I00 on the panel 40 whereupon the portion of the extension 39 outwardly of the score or fold line 36 is folded on said score or fold line 36 to bring aportion of the panel 44 into engagement with said adhesive. Adhesive is then applied to the now exposed surface of the panel 43, as seen in Fig. 1, or, adhesive, indicated byreference numeral IOI, is applied to the carton bottom panel whereupon the extension is folded on the score or fold line 32 thereby bringing the panel 43 and panel25 into face contact. This folding now exposes the unexposed face of panel 42, as seen in Fig. 1, and to which now exposed face of panel 42 is applied a band of adhesive or the adhesive may be applied to the portion of the panel 09 which constitutes the glue flap thereof by applying same to its under surface illustrated at I02. At this time the blank extension 3I is folded on the score or fold line 66 bringing the under surface, as seen in Fig. 1, of panel 99 as the exposed surface whereupon the said extension 3| is again folded on the score or fold line 29 thereby bringing the panels 42 and 99 into face contact with the adhesive I02 therebetween. The folded blank is now in the position illustrated in cross-section in Fig. 2 and is subjected to pressure 'for permanently adhesively uniting the parts to one another The blank is in its folded or knocked down position in which it is shipped to the user for subsequent erection and use. I

From the foregoing and as disclosed in the drawings it will be noted that the first side wall inner wall member or panel 40 is of less depth than'the side wall outer member or panel 38 while the corresponding panels 69 and 61 which respectively form the inner and outer wall members of the second side Wall are of substantially equal depth. Also it will be noted that the end walls inner wall members or panels 88 are of less depth than their respective outer wall members or panels 80. The supplementary bottom or panel 43 while of substantially the same length as the main bottom panel 25 is of less width than said parent from the disclosure in Figs. 3,4 and 5- and will presently be made clear. y 11 c 1 d s l lszla 91" YB Q TPPKQE do not have attached theretojthe spacer flaps 4 ther b dis qs ne ths d ste we bers orpanels 39 and 68 to be parallel with the bottom n a d-With e side. wsll i n sand n rws m m e s a alle $99 1 5 191 9 an to het iton t minanek The. sp er: l fl or p ne 4. a ne w th ,zt e-inn r .w member a e A ex nds. f om the-s smit m 2 to e top w. m m er-..'-T n r .-W.a.11. m mb l- 9;. 1sswi ene ends fr m t e tQ bottom P ne 25m. th 36. 1?

The end wall extensions are then folded on their various score lines after first upwardly, from the position shown in Fig. 1, bending the end wall inner wall member'spacer flaps 94, and 99 to be normalitotheextension. It .is of course understood 'that the tucking flaps SI, 52, I9 and 11 were folded to be transversely of the carton and the spacer tabs 54, 55,19 andfiq bent to be parallel to the cartonbottom25. The upward raising or bending-,ofithe extensions al and 82 automatically. folded the corner pieces'I03 on themselves on their respective diagonal fold or score I04 so that the: actuation of the end walls top wall members,- inner wall members and spacer flaps 89' enfolded the, same. Justatthe time that the end wall inner wall members or panels 89are brought to their final positions the locking lugs 99 and'9'l thereof snapped into the aligned side walls innerwall members elongated perforations 63'and 98 and 64 and 99. The carton is now in the erected position-of Figs. 3,-=-4;and,5.

The modification illustrated in Figs. '6 to 10, inclusive, presents a box or carton which does not have spaced apart wall membersor hollow walls but instead utilizes, side-andjendjwall's that are merely ,of double thickness. Accordingly gthe blank illustrated in Fig. '6 includesjmerely'the carton bottom wall or panel 25 from oneside of 1 which projects an extension3I having the panels 61 and 69 which are of'substantially the same height and in which the panel 69 is utilized, in part, as the glue flap. Thepanjel169 has projectingfrom its ends tucking flaps IG'jand 11' which since the end walls, aswillpresently, be made clear, are not of a spaced apart construction but merely double thickness. r J

The mo'dificat'ion'dis'closed in Figs: l"1-'t'o*15 is qnite simil'a'r tothe disclosure in'Figs. 1 to fif'in elusive; in that the-box o'r' carton is'protided with walls each of' which is formed of "s15acil apart inner andoiiter members orof hollow construction.

Thefblafik' ofFig; 11 is 'foldedandsecnred in its folded position, as seen in Fig; 12, in substantially the same manner asabove described in connection 'withthe blank inFig. 1, and it'isin this condition that the blank is shipped"to"the user. The user upon desiri'ngto set up thecar ton from the blank of Fig. 11 follows the same steps as'above'de'scribed in'conne'ction' with the carton form'ed'fro'nr the blank of Fig. 1 except, insteadof snapping locking'lugsww and 91 into sidewall apertures; snaps'the'lockinglugs or tongues IGS'into the slitspmvidedinthe carton platform by the U-sha'pe cut I I I therein.

As'will be seen from Figs. Hand 15 the plat form'M' of themodification is'anchored along its sides against any movement while the'ends-ale similarly anchored, downwardly, by the supporting': flaps 5B and 59 and upwa-rdlm'by the end walls inner Wall'members or pan'els88".

In the cartons-or boxes hertoforedescribed the platformwasheldin position by adhesively s'ecmingthe same to and intermediate the side walls and by" providing 'it Witha sub-base or carton-bottom paneladhesivelysecured to the said niain bottonipanel; Inthe modification-illustrated in Figs. 16 to '20, inclusive, means are provided'which do 'not depend on adhesive'for anchoring or secu'ringtheparts in position and this modification will nowbe described.

Accordingly, andas seen in Fig. 16; the blank comprises a panel H2 constituting the bottom or-"baseofthe carton having its sides and ends defined, respectively, by score or fold-lines-II3 and II4-"and4 I5 and H6. Integral with thebottom cartonsidethrough-the score or fold line I'I3-is an extension IITlongitudi-nally divided 'by score or fold lines I I8, -I I9 and I20, thereby'providing in said extension panel -I2I in theerected cartonforminga side wall outer Wall member, a panel -I22, forming inthe said side wall a top-wall member, a-panel I23, forming in the side Wall an inner-wall member, and-a-fpanel I24 forming in tbe carton a glue flap;

Similarly, and connected with the bottom panel '2 through'the score or fold line H4 isan'e'xtension-|25 of greater length-than the'extension II 'I and forming in'the erected carton the secand side wall and the platform wherefore said extension 12-5 isdivided, longitudinally, byscore or fold-lines-- I26, I2'I,I2 8' I29 and I30; The said score or fold lines; I 26to-|30; inclusive, -form in the extension I25- the cartonsecond side wall outer wall member or panel -I3 I aportion of the second side wall inner wall member or panel I32, he l m res ll-T a; cer..- t free end of the platform I33 or panel I34, 9. sub- 9 bottom member or panel I35 and. a glue fiap or panel I36.' The ends of the side walls outer wall members or panels I 2| and I 3| are defined by score or fold lines I31 which integrally hingedly connect thereto corner pieces I38 which are in all respects similar to the corner pieces I03 dis closed in Fig. 1 and constitute bellows corners, for which purpose each of the corner pieces I38 is provided with a diagonal score or fold line I39.

The carton bottom or panel II2 hasintegr-ally hingedly connected with its ends through the score or fold lines H and 6- similar end walls forming extensions I40 and MI which are substantially identical with one another wherefore it is deemed sufficient if but one of them be described.

Accordingly, extension I40 is provided intermediate ends with a score or fold line I42 thereby providing a panel I43 which in the erected carton forms the end wall outer wall member and a panel I44 which in the erected carton forms the end Wall inner wall member. The ends of the end walls inner wall members are each defined by a score or fold line I45 which integrally hingedly'connect thereto the adjacent side of the bellows corner pieces I38.

The first side wallor panel I23 is provided inwardly of its ends with a out line I46 and I4! thereby providing tongues I48 and I49 integral with and inwardly projecting from the glue flap I24 upon the folding of the side Wall panels relative to one another on the score or fold line I20. The platform spacer panel I34 is likewise provided near its opposite ends with cut lines I55 and I5I thereby providing tongues I52 and I53 integral with and inwardly projecting from the sub-base or .panel I35 when the second side wall and platform extension. I25 is folded onits score or foldlines and particularly when folded on the score or fold line I29.

. After the'blank of Fig. .l6,.has-been cut and scored as there illustrated adhesive I54 is applied tothe carton base or bottom panel II2 for a distance inwardly of its score. or fold line H3 and adhesive "I55 is applied to the second side wall outerwall member I.3I as well as adhesive I56 is applied to the second side wall inner wall member portion or panel I32. At this time the extension I I! hasits panel or glue flap I24 turned or folded on the score or fold line I20 onto the panel I23 whereupon the said extension II! is further folded on the score or fold line I I 8 there by bringing the panel I24 into face contact with the adhesive I54.

At, this time or simultaneously with the folding of the extension II! the extension I25 is folded other and it is in this condition that the blank is shipped to the user. It should be noted that the folding of the extension I I! to its knocked down position projects the tongues I48 and I49 inwardly of the carton and resting on the carton base or' panel II2.

Similarlythe folding of the extension I25 projected the tongues I52 and I53 inwardly of the ca'rton'an'd disposed the same; tongues I52 and I53, 'respectivelyon topof the tongues I48 and I49. The user-upon desiring to set iup thecarton aces sofin substantially the same manner as the cartons above described were set up, namely, by raising the side walls outer wall members from their fiat to their upstanding positions and which operation is illustrated in an intermediate position in Fig. 20. It will be noted from Fig. 20 that the raising of the first side wall or the outer wall cuts I55 and I5I formed in the platform member or panel I2I opens or provides openings or apertures I51 in the said side wall inner wall member or panel I23 caused by the cuts I46 and I41 and-into which openings the said lugs I52 and I53 of the carton sub-base or panel I35 are projected in the process of erecting the side walls. Ihe upper edge of the-openings I51 cooperate with the lugs'I52 and I53, after the carton side wallshave beenerectedto their operative positions, in preventing upward movement of the platform or panel I33. The erectionof the carton end walls from the blank of Fig. 16 is completed in the same manner that the end walls of the carton of Fig. 8 from the-blank ofFig. 6 is effected.

From the foregoing it will be noted that the platform of the carton illustrated in Figs.- 16 to is held againstdisplacement vertically ofthe carton in a manner as effective as that above described where the said carton platform is adhesively secured in position. v The modification illustrated in Figs. 21 to 24, inclusive, is quite similar to that illustratedin Figs. '16 to 20, inclusive, except that instead of interlocking the platform through the sub-base or panel 236 against vertical displacementthe said platform is held in operative position by the first side wall resting directly on the platform itself and the modified blank therefor merely-consists in effecting a difference in width of the panels thereof.

Accordingly the blank disclosed in Fig. 21 is modified over that disclosed in Fig. 16 by *having its side wall inner wall member or panel I23"of less depth than that shown in Fig. 16 and of providing an additional panel I58 between the panels I23 and I24 and which panel I58 forms the first side wall bottom wall memberv connected With the panel or glue fiap I24 through a score or fold line I59. The blank -of Fig. 21 isvfurther modified by forming or making the'panelsl33' and I of greater width than the corresponding panels in Fig. 16 and whichpanels are'ofsubstantially the same width as the carton base or bottom panel I I2. In the blank of Fig. 21 the cuts I46 and I41 are not formed in the first side wall inner wall member or panel I23 nor are there spacer or panel I34. 2

The blank of Fig. 21 is supplied with: adhesive in the same manner as the blank of Fig.-l6 and is folded to have the parts secured to oneanother in substantially the same manner as above described whereforethe blank in its knocked shipfirst side wall is erected so that the platform may beprojected below the said first side wall 'to have its bottom wall member 'or panel I58 r'esting'ther'eon in' the final assembly asclearly illustrated in Fig. 23.

should be understood that theplatform of 'iea'ch 'of' the various modifications disclosed in 'thisapplic'ation may have one or: more"-.openings 11 50 therein depending uponthe number and contour of the articles to be displayed, packed or shipped as is usual and acceptedpractice. It should be further noted that in each of the modifications disclosed the knockeddown carton or folded blank is in such positions that equal pressure may be applied to the several layers thereof in effecting an adhesion of the parts and panels to one another which is anessential feature in providing a knocked down box or carton to insure the parts beingbrought to operative positions without breaking the bonds therebetween.

In view of the foregoing it is believed now evident that there has been provided a box or carton which will accomplish the objects initially set forth.
